IMPROVEMENT IN CARBURETERS.

Specification forming part of Letters Patent No. 172,074, dated January 11, 1876; application filed November, 28, 1873.

To all whom it may concern:

Be it known that we, ARTHUR BARBARIN and FRANKLIN ROBERTS, both of the city of, NewlOrleans, State of Louisiana, have jointly invented certain Improvements in Oarbureting- Machines, of which the following is aspecification:

Our invention refers particularly to details of construction, whereby the defects existing in carbureters now in use are remedied; and consists in securing auxiliary curtains between the outer curtains, whereby six' interior surfacesare exclusively employed to convey by capillary attractionthe fresh hydrocarbon to theouter surfaces of the curtains, which-are exposed to the air; but a reference to the annexed drawing will at once, and very clearly, indicatethenature of ourimprovements.

1 Figure 1 is a vertical section of a small can bureter as placed upon and supported by a metal disk or plate, y, andframe y y', secured to an ordinary meter-pump, A.

3 represents the shell of the carbureter; G, the top of same; It, the gas-conduit; R, the oil-inlet, with its screw-cap 1' and pipe 1',- s, the air-vent; t, the draw-off pipe, provided with the screw-capt; and p, the central air. pipe, to supply the carbureter with air. With in the shell Bis fitted andsecured air-tight a. circular metal plate or disk, D, upon which the fibrous material is fastened andsupport ed, soas to form an extended spiral or volute scroll-curtain, d, as shown at Fig. 2, which represents abottomview of the same, form.

ing a passage, d, of anysuitable lengthand width, for the purpose'of conducting the air and gas which. may be forced into it. To

' fasten the fibrous material-permanentlyto the disk D we;employ a sheetmetal strip, a, of about three-quarters ofan inch in width,and of any suitable length, and fold one of its edges, c, lengthwise, soas to producea nar- -rowelongated groove or clasp on one side,

and a larger elongated surface on the other side, as shown at Fig. 3. Fibrous material (cottonfabricwill answer) of the proper length and width isthen folded over, so as to form four or more independent curtains in contact with each other. These are placed upon an ordinary wire, I), so as to be supported. by the; same, and form six or moredistinct interior posed surfaces, as shown at Figs. 1 and 4. When this is accomplished both the wire and that part of the curtain hanging upon the same are inserted into the groove or clasp u, and firmly secured in the same by serrating the lower part of the clasp underneath-the wire and against the other part ofthe strip, as shown atFig. 4. t

To facilitate operation in the construction, and application of these curtains to the disk, Dwe reserve the right of using and-applying; sections or short metal strips in lieu of asingle metal strip, as before described, whenever, it may be advisable soto do. y 1' The object of securing these curtains in the manner described is to prevent the possibility of their getting loose, as well as to facilitate the labor of the workman when soldering the upper part of the grooved edge of the metal strip a to the disk D, by bringing the larger heatedsoldering-iron toprevent the charring or burning of the f brous material, besides which the flexibility of the strip or sectionsof istrips admit of alarger variety of. forms which 10f the spiral shape vrepresented upon the drawing, to which form we. do notconfine ourselves. I I.

By our arrangement it will readily; be per-l ceived that the sixinterior surfaces of the hanging curtains (before referred to) are not :acted upon by theair or gas which may be forced into the carbureter, provided thatthe but that they are exclusively employed to, convey the fresh hydrocarbon charges to the said outer surfaces of the curtains exposedto the direct action of the air or gas by meansof,

tactwith each other, as well as with those of the outer curtains, as fast as the same may be evaporated. y y h t To prevent theseparation of the lower ends of these curtains, and tocompel their imme; diate contact with each other, so to form PATENT CFFTCE.

or unexposed and two distinct exterior or ex surface of the strip in direct contact with the may be, given to the hanging curtainsin lieu outer fibrous curtains be sufficiently thickp their capillaryproperty and immediate con an even surface anthregular channel, (1, into which the air or gas may be forced to be carbureted, we secure the same together at certain distances by means of the ordinary paper fastener l.

To prevent the collapse of the end fof the curtains after securing the same to the disk D a short vertical metallic spiral guide, E, is secured to the center of the said disk, so as to surround the central hole 0, for the purpose of supporting the said endf by sewing or otherwise connecting the same together, as well as to avoid the escape of air or gas at that particular point, while at the same time serving the purpose of central support to the disk D when the same is in position Within the carbnreter.

To prevent the collapse ofthe discharge end 9 of the curtains, an additional support, f, consisting of a folded vertical metal strip, is soldered upon the edge of the disk D, at the terminus of the fibrous curtains for the purpose of holding the said discharge end in its proper position, by inserting the same within the fold and clasping both together, as shown.

On applying the disk D with its suspended curtains within the shell B of the carbureter, the lower end of the vertical spiral guide E bears upon the center of the convex bottom of the same, and supports the disk in its proper position. The edge of the disk is then soldered around, and to the inner surface of the shell, air-tight, and the lower end of the vertical section 19 of the air-pipe, previously provided with the cap 12 at its upper end, is introduced through the sleeve 0 and the central hole 6 of the disk D, extending in its downward course through the center of the spiral 'guide 0, and through the bottom of the carbureter, a little below the outside surface of the same, so as to be easily connected to its horizontal section 19 by any suitable means.

After this is accomplished, the cap a, previously secured to the upper end of the vertical section pot the air-pipe, fitting and forming the cover of the sleeve 0, is soldered to the same air-tight, and then the outside end of the vertical section 19 of the air-pipe passing through the bottom of the carbureter, on being soldered to the same, precludes leakage, as well as a collapse of the bottom of the apparatus. The top or cover 0 is next applied and soldered to the shell B, when the carbureter is ready for operation.

In manufacturing large carbureters, owing to the quantity of hydrocarbon which they require, we have found it necessary to prevent the collapse of their bottom, (frequently caused by the weight of the oil,) to run the central vertical section 19 of the air-pipe entirely through the cap nof the sleeve 0, through the top and bottom of the carbureter, so that after soldering the cap a to a proper distance upon the said vertical pipe and to the sleeve 0, both the upper and lower ends of thesaid vertical air-pipe maybe properly secured to the top and bottom of the carbureter, to preclude all possible chance of leakage, and of a collapse of the bottom of the apparatus.

Although upon the drawing no stop-cock is shown to regulate the flow of air into the carbureter, yet the same may be applied for that purpose at any convenient point of the airpipe 19; and in lieu of the V-shaped opening or air-outlet 2, cut in the upper part of the vertical pipe 19 for the admittance of air through the space formed by the sleeve 0 into the spiral channel d, other suitable openings upon the said pipe at or near the same point may be employed with equal advantage.

To free the horizontal section 1) of the airpipe of the water which may, from condensation or other cause, fill the same, the end 3 of the said pipe should always be higher than the end 4, which is connected with the vertical section 12 of the air-pipe,'so that the water accumulating in the same may, of its .own

gravity, drop back into the drip-pipe w, and from which it may be withdrawn by means of an ordinary stop-cock, or by unscrewing the cap 00.

The operation of our carbureter is as fol: lows: After the machine has been properly located, and the main gas-pipe of the building connected to the gas-conduit R of the carbureter, the screw-cap r of the oil-inlet R is withdrawn. and a funnel screwed in its stead to the inlets throat; then the vent s is opened and the gasoline poured into the funnel to be conveyed into the carbureter by means of the pipe 1" of the oil-inlet, which runs through the hole 1' of the disk D, and extends to near the bottom of the carbureter. As soon as a few drops of the oil begins to trickle out of the vent the operation is stopped, the funnel withdrawn, and the screw-caps of the oil-inlet and vent are returned to their respective places. Water is then poured into the pumpcasing up to and a little above the central axis of the pump-shaft, and the weight wound up by means of the crank w. When this is completed, the air and gas stop cocks are opened, and the air, through the action of the weight and of the pump, is forced into the: carbureter through the V-shaped opening of the central vertical section 19 of the air-pipe, follows the space left between the inner surface of the sleeve'o and the outer surface of the pipe, descends into the channel d formed by the spiral guide 0, and the fibrous curtains thereunto attached become saturated with the hydrocarbon vapor, and escapes through the perforation 5 into the gas-conduit B, fI'OIIl' whence it is conveyed by pipes for consumption. i Although on the drawing the carbureter is represented as being placed above the pump, so as to form a compact self-generating gas apparatus, it is proper to state that-the machines work with equal advantage when the carbureter and air-pump are placed apart from each other. This we have to do occasionally, especially when the size of the apparatus exceeds sixteen lights.

We have also ascertained by practical experiment that'the weight of our machines can be Wound up when the lights are burning without extinguishing the same, and that our machines will operate longer at their full-rated capacity than any other machine known to us. This is attributable to the peculiar manner of constructing our curtains, and especially 'to our new method of supplying fresh charges of the hydrocarbon to the within exposed or evaporating surfaces of the fibrous material as fast as evaporated.
